Mousing around constantly pisses me off (and aggravates a mild rotator-cuff injury I picked up a month or so ago). Give me a console and a well-designed text editor, and I'm much happier than if I have to constantly click and drag. (After all, communication has evolved past the level of crude gestures and pictograms... perhaps interfaces should, too. :-)

Of course, you can do all that on a Windows system (and I have); cygwin (or msys, which I prefer), bluebox, and a slew of smaller extensions let you make a Windows box feel fairly Unix-like, and still be able to play new-release commercial games. It's just nice not to have to go to all the trouble.
